1. Context 1.2. Lack of Inspectors Limited number of courses and graduations in NDT Long duration to get required experience High age of inspectors in average 1.3. Resulting Production Ranges Most of NDT operations are final checks (when components have the highest added value) Few intermediary NDT operations along the manufacturing process 1.4. NDT perceived as an Extra-Cost Though it actually increases the products value, so that they are delivered in conformity with the quality requirements 11th ECNDT - October 2014 - Prague, Czech Republic Slide # 5 / 20

2. Possible Improvements 2.1. Direct Readout Instruments Display measurements in dimensional or electrical units either as digital readout or an analog display Do not require special skills or knowledge to set up the instrument 2.2. Level 1-Limited Employer certification level Exam: 10 + 8 questions (against 40 + 30 for Levels 1 & 2) Validity: 1 year (against 5 for Levels 1 & 2) These two drivers led us to develop a new generation of instruments: 11th ECNDT - October 2014 - Prague, Czech Republic Slide # 7 / 20

5a. Conclusions Several solutions were developed to assist operators in the diagnosis phase, and release faster components in manufacturing plants and aircrafts in maintenance: Detection of delaminations around drilled holes Detection & sizing of damages after impacts Thickness measurements after blending or machining These solutions are available on the which are designed to respond to industry problems, mostly in the aerospace sector: Lack of certified inspectors, Human factor affecting inspections reliability, Use of UT1-L and ET1-L operators for simple inspections after each manufacturing step (in addition to final NDT performed by experts) to repair or reject bad components as soon as possible 11th ECNDT - October 2014 - Prague, Czech Republic Slide # 17 / 20
5b. Continuation Upcoming software applications with Cracks removal: detection of loss of Al cladding on metallic fuselage Corrosion: automatic sizing of affected surfaces Drilling in laminates: automatic sizing of delaminations Other Progress Directions: Automatic sorting of components tested by machines (accepted vs rejected see presentation during session 22 on Thursday) Geolocalisation Augmented reality Remote assistance with OMA Main Driver: to easy the work of inspectors 11th ECNDT - October 2014 - Prague, Czech Republic Slide # 18 / 20
